Patented Sept. 1, 1942 UNITED STATES PATENT OFFICE BRINTING MACHINE Eugene H. Klingellu ss, Brooklyn, N. Y., assignor to Klingrose Machine Corporation, Brooklyn, N. Y., a corporation of New York Application October 10, 1941, Serial No. 414,396

9 Claims. (Cl. 10l'350) This invention relates to new and useful improvements in a continuous web printing ma-" operative with a cylindrical form which is mounted in a casing supporting a cooperative furnishing roller and ink supply. It is proposed that slides support said casings, and that a mechanism be provided for simultaneously moving said slides to simultaneously separate said counter pressure drums and cylindrical forms.

The invention also relates to a printing machine in which the printing units have meshing gears on the counter pressure drum and the cylindrical form. It is proposed that means be provided for limiting motion of the slides previously referred to, to prevent disengagement of said gears while said drums and forms are separated, and said means to be controllable to permit simultaneously disengagement of said gears, when desired.

The invention also proposes an arrangement whereby the slides may be individually moved to individually disengage the meshing gears, when this is desired.

The invention also relates to novel improvements in each printing unit characterized by a novel arrangement of ink pan and doctor blade for the furnishing roller. It is proposed to mount the ink pan in a certain way so that it is readily removable when desired. It is also proposed to oscillate the ink pan in a certain manner durin the operation of the machine.

The invention also proposes a novel arrangement for supporting and adjusting the pressure of the doctor blade against the furnishing roller.

Another object of the invention relates to a novelarrangement in a continuous web printing machine having a plurality of printing units, which arrangement relates to a feed mechanism for assisting in feeding the web through the machine associated particularly with the first and last printing units. A construction is proposed whereby this feeding mechanism, at these two points, may be simultaneously placed into and disengaged from operation when desired. It

a novel arrangement in which a lever moves past a dead center for locking the parts in operative positions. With this arrangement the lever may be moved from past its dead center position, and then the feeding mechanism may be rendered inoperative.

The invention also relates to a novel arrangement of heating units for each of the printing units. It is proposed to characterize these heating units by an arrangement whereby a lever which may pass a dead center controls the operative and inoperative positions of each unit. With this arrangement it is a simple matter to project a heating unit into operative position and withdraw it when this is decided.

The invention also contemplates a novel construction of the web rewinding unit. In prior units it was necessary to adjust a moving wheel or part for adjusting the slip of the rewinding unit. This invention proposes a construction in which it is possible to adjust a stationary part for controlling the desired slip.

For further comprehension of the invention,

and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claims in which the various novel features of the invention are more'particularly set forth.

The continuous web printing machine, in accordance with this invention, includes a frame 35 which consists of a pair of spaced side walls 3| and 32 connected together as a plurality with braces 33, see Figs. 1 and 2. A plurality of printing units 34 are mounted upon the frame 35. In the particular machine illustrated in Fig. 1, there are two printing units 34 mounted upon the right hand side of the frame 35 and two printing units 34 mounted on the left hand side of the frame. Each of these printing units 34 includes a counter pressure drum 35 which is rotatively mounted upon the frame 35 and which is cooperative with a cylindrical form 35 which is mounted on a casing 31 supporting a cooperative furnishing roller 33 and an ink supply 33 (see Figs. 3 and 17). The casing 31 of each printing unit 34 essentially consists of a pair of laterally spaced walls, see Fig. 2, and each wall is mounted on a slide 45, see Figs. 3 and 5. These slides 45 are associated with means for simultaneously moving said slides 45 to simultaneously separate said cylindrical forms 35 from the counter pressure drums 35. This means is characterized by arms 4| connected with the slides 45 (see Figs. 3 and 4) and associated in a certain way with sprockets 42 engaged by an endless chain 43, as will be hereinafter more fully described.

35. Means is provided for limiting motion of the slides 43 to prevent disengagement of the gears 45 on the cylindrical-forms 35 and the gears 45 on the counter pressure drums .35. This means may be best understood by examining Figs. 1 and 7. The endless chain 43 passes over a pair of laterally spaced sprockets .41 mounted on the wall 3| of the frame 35. The chain 43 then continues and engages beneath a sprocket 43 which is mounted coaxially on a drum 43 rotatively mounted on the said wall 3|.

The drum 43 is provided with a gear 55 which meshes with a gear 5| rotatively mounted on the wall 3|. The gear 5| is coaxially fixedly connected with a hand wheel 52. The drum 43 has a projecting lug 53 which in the position of the parts shown in Fig. 7 engages against a pin 54 projecting from the wall 3|. This limits turning of the drum 43 any further counterclockwise. However the drum 43 may turn clockwise until the projection 53 strikes against a pawl 55. This pawl 55 is pivotally supported upon a pin 55. It is provided with a handle 51 by which itmay be conveniently moved to an inoperative depending position, when desired. The hand wheel 52 may be turned so as to indirectly move the endiess chain 43 so that the projection 53 moves between the pin 54 and the pawl 55.

When the projection 53 is against the pin 54, the arms 4| will be fully retracted so that the slides 45 are retracted and the cylindrical forms 35 engage the counter pressure drums 35. The hand wheel 52 may be moved so that the projection 53 engages the pawl 55 and then the arms 4| will be slightly extended so that the slides 45 are slightly extended and the cylindrical forms 35 disengage from the counter pressure drums 35. However, the gears 45 and 45 maintain their mesh. If desired, the pawl 55 may be pivoted clockwise and allowed to depend. Then the hand wheel 52 may be turned further so as to further move the endless chain 43 so that the arms 4| are further extended, further extending the slides 45 and thus disengaging the mesh of the gears 45 and 45.

Means is also provided for individually moving the slides 45 so that the gears 45 and 45 of any printing unit may be disengaged. This means may be best understood by an examination of Figs. 1, 3 and 6. The sprocket 42 of each printing unit is loosely mounted on a rod 53 which is turnably mounted on the walls 3i and 32 of the frame 35. A handle 53 is fixedly mounted on each rod 58. Each handle 53 is provided with a bolt 55 engaging a keeper opening 5| formed in the sprocket 42. The bolt 55 is urged into operating position by a spring 52. The bolt 55 has a reduced shank 53 passing through a stationary bushing 54. A knob 55 is mounted upon the outer end of the shank 53. The spring 52 works between the bushing 54 and the head of the bolt 55. The arrangement is' such that the knob 55 may be pulled to disengage the bolt 55 from the key opening 5|. Then the handle 53 may be turned for projecting or retracting the arms 4| without any motion of the sprocket 42. Each arm 4| is mounted upon an eccentric 55 fixedly mounted on the rod 55. Thus when the rod 55 is turned the arms 4| thereof will be extended or retracted.

Each casing 31 is adjustably mounted on its slides 45. More specifically, each slide 45 has a lug portion 55, see Fig. 3, upon which a screw." is rotatively mounted. The outer end of each 31. The arrangement is such that a pair of the handles I8 may be turned for manually adjusting each casing 31 .to control the set pressure between each cylindrical form 36 and its counter pressure. drum 35.

. An arrangement is also provided for controlling the pressure between the furnishing roller 38 and the cylindrical form 36 of each printing unit. This arrangement includes brackets 12 slidably mounted on each casing 31 by means of retaining strips 12d, see Fig. 18. Each casing 31 is provided with lugs I3 through which screws 14 are rotatively mounted. These screws 14 threadedly engage the brackets I2. The screws 14 are provided with knobs 15 on their outer ends. The arrangement is such that a pair of the knobs 16 may be turned for moving the brackets 12 of one printing unit forwards and rearwards and so adjust the pressure between the furnishing roller 38 and its cylindrical form 36 of the printing unit.

Each ink supply 38 includes an ink pan 16 which has a pair of bars I1 attached on its bottom, and projecting from its sides. 11 are releasably supported by flap members 18. These flap members I8 are pivotally mounted by pintles 18 upon auxiliary brackets 88 which are fixedly mounted by lugs 8I upon the brackets I2. The flap members 18 are releasably supported at their free ends by small latches 82. Each latch 82 is pivotally held near its top by a pintle 83.

Intermediate of its ends it is formed with a shoulder 84 which catches the end of the flap member 18. A spring 85 acts between each auxiliary bracket 88 and the top end of the latch 82 for urging the latch into closed position. The construction is such that the latches 82 may be opened and then the flaps 18 lowered to release the bars 11. The ink pan I6 is then free to move downwards and out of the ink supply unit.

Means is provided for oscillating each ink pan 18. This means includes a worm 86 mounted on the shaft 81 of each furnishing roller 38. Each worm 86 meshes with a cooperative worm 88 rotatively supported on a bracket 88 mounted on the bracket 12. Each shaft 81 is rotatively supported on a pair of the brackets I2 by ball bearings 120. with each worm 88. Each link 88 is pivotally connected with an arm 8| slidably mounted through the bracket 12. The free end of each arm 9| is provided with a block 82 pivotally held in place thereon by a stud 82a, and said block is slidably engaged in the slot 83 formed in a transversely positioned arm 84. Each arm 84 is pivot- .ally supported at one end by a pintle 85 on said bracket 88. Intermediate of its ends each arm 84 is provided with a stud 86 which extends through an elongated slot 81 formed in the auxiliary bracket 88. Each stud 86 has a reduced end 86a which engages into an opening in the adjacent arm IT. The arrangement is such that the rotations from the worms 86 and 88 are transmitted to oscillate the arms 8i and 84 which indirectly oscillate the adjacent arm 11 and thus the ink pan I6.

Each ink pan I6 is provided with a doctor blade 88 which is cooperative with its furnish ing roller 38. Each doctor blade 88 is supported on a member 88 which is mounted across two blocks I88 mounted over the sides of each ink pan I6 in a certain way. Each block I88 has a slot I8I formed inwards from its bottom end.

A link 88 is eccentrically connected These bars The sides of the ink pan I8 engages in these slots. Consequently one half of each block is outside of the side wall 01' the ink pan, while the other half is inside. The member 88 is mounted across the inside halves of the blocks I88. The outside halves of the blocks I88 are provided with outwardly projecting pins I82 which are pivotally supported. These pins I82 engage into slots I83 formed in blocks I84 attached to the ends of the ink pan I6. A latch I88 is pivotally mounted 'on each block I84, and engage over the open end of the slots I83 so as to normally hold said pins I82 releasably in position. I

A pair of hook shaped rods I86 have their inner ends pivotally connected with the blocks I88 at points above the pins I82. The outer ends of the rod I86 are formed with threads l8l which threadedly engage bushings I88. These bushings I88 are rotative through brackets I88. Each bushing I88 has a head II8 by which it may be turned. Each bracket I88 is swivelly supported by a stud III (see Fig. 16). These studs III engage through supports II2 attached upon the front wall of the ink pan I6. The arrangement is such that the knobs II8 may be turned for pivoting the blocks I88 so as to cause each doctor blade 88 to engage under selective pressures with its furnishing roller 38.

The ink supply 38 is somewhat similar to the ink supply illustrated in my co-pending application, Serial No. 329,873, filed April 16, 1940, and covering a Printing fluid distributor for printing machines. From this prior application it may readily be understood that the furnishing roller 38 is engraved to have a plurality of small ink wells on its surface. The doctor blade 88 scrapes the ink oil the furnishing roller, except for the deposits in these wells. The cylindrical form 36 has its printing surface constructed from resilient material, such as rubber. This cylindrical form comprises the printing form for the printing unit. However, because of its soft construction it is capablepf entering the ink wells of the furnishing roller 38 and picks up the ink which is subsequently transferred to the web which is being printed.

The ink supply mechanism of the various printing units 34 are substantially identical, except for the fact that the doctor blades 88 are arranged on different sides of the furnishing rollers 38 for the reason that certain of the fumishing rollers are delivering ink at sides opposite to the delivery sides of the other furnishing rollers during the operation of the printing machine. In Fig. 19 the doctor blade88 is shown against the outer side of the furnishing roller 38. In Fig. 15, which shows the ink supply on the other side of the machine, the doctor blade 88 is engaging against the inner side ofthe furnishing roller 38. For this reason it is required that short hook rods I86 be used in lieu of the long hook rods I86 shown in Fig. 16. Furthermore, the supports 2' which support the studs III are shaped somewhat diflerently than the supports II2. In

other respects the parts are identical and like parts have been given the same reference numerals so that they may be readily identified.

A single source of power is used to operate the various, printing units 34. More specifically, an

electric motor H3 is provided with a pulley II4 over which belts II5 engage. These belts 6 engage over a pulley II 6 upon a horizontal shaft II'I rotatively supported in bearings II8 mounted on the rear wall 32 of the frame 38. The horizontal shaft II! has its ends engaging into a tical shafts I26 pass through these'casings III and are rotatively supported by ballbearings I26a, see Fig. 13, whichare mounted on the rear wall 32. The ends of the horizontal shaft III are provided with bevel gears I2I which mesh with bevel'gears I22 mounted on the shafts I26 andv located within said casings III. Thus the shafts I26 are being indirectly driven by the motor H3. The ends of each shaft I26 is provided with a worm I23 which meshes with a complementary worm I24 mounted on the shaft I26 of the adiacent counter pressure drum 36. The worms I23 and I24 are located within casings I26 mounted on the said back wall 32.

An arrangement is provided for controlling the rotative registration of each cylindricalform 36. For each cylindrical form there is a handle I21 mounted on a rod I26 rotatively supported in a bearing I26 mounted on the wall 3I of the frame of the machine. Each rod I26 is provided with a worm I36 meshing with a complementary worm I3I on a shaft I32 extending across themachine to the wall 32 and entering the casing I26. Each shaft I32 is provided with a gear I33 meshing with gear teeth I34 on a slidable collar I36 vertically slidably mounted within the eas- I6I. From this point the web I360. continues over a group of guide rollers I62, I63, I64, I66, I66 and I61 mounted on an auxiliary frame I66 of the machine. The web then continues upon a rewind roll I36.

A rod I66 is mounted between the walls 3| and 32 and supports bell cranks I6I- at their centers. A cooperative wide feeding roller I62 is mounted upon one of the arms of the bell cranks I6I and is engageable against the web I330 ata point adiacent the feeding roller I46. Another rod I63 is pivotally mounted between the walls 3I and '32 andsupports bell cranks I64 which are provided with a pair of narrow feedingrollers I66 engageable against the web I334: at a point adjacent the feeding roller I66. A rod I66 is adiustably connected with the free arms of the bell cranks I6I and I64. This is accomplished ing I26. This slidable collar I36 supports the said worm I23 with the aid of thrust bearings I360. The arrangement is such that each handle -I21 may be turned to indirectly raise or lower worm I23. This causes a slight rotative turn of the worm I24 and shaft I26 and thus the counter pressure drum 35 is being turned. Since this drum 36 is geared with the cylindrical form 36 the latter is being adjusted. This arrangement permits an individual adjustment of each of the cylindrical forms. Each cylindrical form 36 may be axially adjusted by the usual screw I36, see Fig. 3, which is mounted on the casing 31 and which engages a flange I31 connected with the cylindrical form 36. r

Brackets I36 are mounted upon the frame 36 and support a web supply roll I33. More specifically, this roll is mounted on a shaft I46 which is supported in slides I4I adjustably mounted on the brackets I36. A screw I42 is rotative on one of the brackets I36 and threadedly engages the slide I4I. The other bracket I33 supports a pivotally mounted member I43 (see Fig. 11) turnable on pivot I43a which supports the other end of the shaft I46. The arrangement is such that the screw I42 may be turned in one direction or the other to horizontally move one end of the shaft I46 and so adjust the supply of the web to discharge straight. A brake I44 is mounted upon the pivotally mounted member I43 by which an'adiustment may be made to prevent the web roll I36 from unwinding too fast.

From the roll I33 the web I36a extends over a guide -ro11er I46 and then continues over by threads I61 on the rod I66 engaged by nuts I63 abutting blocks I66a. pivotally mounted on the bell cranks. A link I66is pivotally connected with the rod I66 and is pivotally connected with one end of a lever I16 which is pivotally mounted intermediate of its ends by a pintle I 1I- mounted on the wall 3|. The other end of the lever I16 pivotally connects with a lever I12 which is provided with a handle I13.

Another lever I14 is pivotally connected with the end of the lever I12 having the handle I13. This latter lever I14 is pivotally mounted by a pintle I15 upon the wall 3|. With the parts as illustrated in Fig. 1 the front end of the lever I14, that is the end having the handle I13, is past the dead center of the pivot I15 and resting against a stop pin I14a. This looks the levers in the positions shown, and locks the cooperative feeding rollers I62 and I65 in operative positions under pressure against the feeding rollers I46 and I56. When desired the handle I13 maybe moved upwards and held against a pivotally mounted catch I16 and this causes the lever I16 to pivot counter-clockwise about the I pintle "I so as to indirectly pivot the bell cranks I41 and then against the counter pressure drum 36 of the second printing unit 34, and then continues beneath a guide roller I46 to the counter pressure drum of the third printing unit and up over a guide roller I46 and over the counter pressure drumof the last printing unit. From this point the web I33a continues over another feeding roller I66 and then over. a guide roller |6I and I64 to disengage the cooperative feeding rollers I62 and I65 from the feeding rollers I46 and I66. The feeding roller I46 is driven by a gear transmission consisting of the gears 246a and 2461) connected with the shaft of the adjacent counter pressure drum 35, (see Fig. 3). The feeding roller I56 is driven by a gear drive transmission consistingof gears 241a, 2411) and 46 (see Fig. 2) connected with the shaft of the adjacent counter pressure drum 35.

The printing machine is provided with a heating unit for each printing unit 34. These heating units are substantially identical though they are of slightly different construction from each other. However, the heating units immediately past the first printing unit 34 with relation to the web supply roll I39 as shown in Fig. l, and the third printing unit 34- are absolutely identical. Each of these heating units includes a pivotally mounted frame I16 which is pivotally supported by a pintle rod I16 upon brackets I86 mounted upon the side walls 3I and 32 of the frame 36, see particularly Fig. 3. These brackets I66 are also used to support the slides 46. Each bracket I36-has a top track portion I86a of- U-shape in cross section (see Figs. farm 5) in which the slides 46 are mounted. The base portions of the casings 31 are also mountedin said track portions I66. Retaining strips I661) hold these parts on the track portions. Each bracket I86 has a slot I6I through which a pintle I82 passes.

These pintles I32 are mounted upon the free ends of the arms 8|. These pintles I82 are connected with the slides 88. An electric heater I88 is adjustably mounted upon'the free end of the frame I18. This heater is provided with a trunnion I88 which is engaged by a clamp device I85 formed on the frame I18. The details of the electric heater I 88 will not be given in this specification as it forms no part of the invention. However, the clamp device I85 makes it possible to place the heater I88 at a proper angle so as to be parallel with the adjacent section of the web I88a.

A radial arm I88 is fixedly mounted on the pintle rod I18 and pivotally connects with a link I81 which in turn is pivotally mounted upon the outer end of an arm I88 which is fixed on a pintle I88 mounted through one wall of the bracket I88. A handle I88 is mounted on the pintle I88. The link I81 is pivotally connected with the radial arm I88 by a pintle I8I. This pintle I8| is slightly below dead center of the pintle I88. The arm I81 rests against a pin I82 mounted on the bracket I88. This pin prevents the arm I88 from moving any further counter-clockwise from its position as illustrated in Fig. 3. Thus the parts are locked in the position as here illustrated. However, the handle I88 may be further moved through a distance of substantially 188' so as indirectly to pivot the frame I18 counter-clockwise. This moves the of the threads 2I8 and abuts the other end of the roller 2| I. The shaft 2I2 is rotatively supported in bearings 2I8 and 2" mounted upon brackets 2I8. The shaft 2|2 is provided with a gear 2I8 which meshes with gear teeth 228 formed upon a clutch section 22| having an annular clutch lining member 22Ib. This clutch section 22I with the aid of ball bearings 22|a is freely rotatively mounted upon a stationary stud shaft 222. e

The stud shaft 222 is mounted on one of the brackets 2I8. A complementary clutch section 228 is also freely rotative on the stud shaft 222 with the aid of ball bearings 228a. This clutch section 228 is provided with a sprocket wheel 228. A thrust bearing 225 is mounted on the stud shaft 222 adjacent one side of the clutch section 22I. A spring 228 is coaxially mounted on the stud shaft 222 and bears against the thrust bearing 225. A hand wheel 221 is threadedly mounted on the stud shaft 222 and controls the tension of the spring 228. The arrangement is such that the hand wheel 221 may be turned in heater I88 from its operating position and it is now inoperatively depending from the pintle rod I18.

The seconding printing unit is provided with a heating unit which includes a frame I85 pivotally mounted on a pintle rod. I88. An electric heater I81 is supported on the frame I85. One side of the frame I85 is connected with a link I88 by a pintle I88. The other end of the link I88 is pivotally connected with a small arm 288 which is fixed upon a pintle rod 28I rotativethrough the side wall 8|. The outer end of this pintle rod 28I is provided with a handle 282.

' A stop pin 288 is mounted on the wall 8| to limit clockwise turning of the small arm 288 past the dead center of the pintle rod 28I. In this latter position of the parts the heater I81 will be parallel and immediately adjacent to the web I88a.

The last printing unit is provided with a heater which includes a pivotally mounted frame 285 which is pivotally supported by a pintle rod 288 on the frame I 58. A handle 281 is connected with one end of the pintle rod 288 by which the heater 285 may be moved. A pin 288 is mounted on the handle 281 and is adapted to strike the end of the frame I58 when the heater 285 is in its operative position. As illustrated in Fig. 1 it. is in its inoperative position and said pin 288 is now resting against a portion of the bracket I88. The handle 281 may be turned clockwise until the pin 288 engages the said frame I58 and then the heater 285 will be parallel and immediately adjacent a section of the web I88a at a point immediately to the rear of the roller I52.

The said rewind roll I88 is associated with a rewind drive. More specifically, the roll I88 is mounted on a roller 2 which-is adjustably mounted on the shaft 2I2. This shaft has threaded portions 2| 8 with right and left hand threads to facilitate positioning of the roller 2| I in correct position. An adjustable collar 2I8 is mounted upon one section of the threads 2I8 and abuts one end of the roller 2| I. A hand wheel 2I5 is threadedly mounted on theother section one direction or the other to force the clutch section 22I at selected pressures against the clutch section 228. Thus the clutch may be adjusted to have a little slip, as desired.

Th sprocket 228 is driven by a chain 288 engaging over a sprocket 28I on a rotative shaft 282 provided with a bevel gear 288 meshingwith a bevel gear 288 on a rotative shaft 285 having a pulley 288, see Figs. 2 and 11. The shafts 282 and 285 are mounted on brackets 258 and NI which are-connected together and mounted on one of the brackets 2I8. An endless belt 281 engages over the pulley 288 and over a pulley 288 on the horizontal shaft I I1.

An arrangement is provided for tensioning the belt 281. This tensioning means comprises an idler roller 288 rotative on a shaft 288. This shaft is adjustably supported in a bracket 2 mounted on the wall 82. Several adjustment screws 282 threadedly engage the bracket 28I and rotatively connect with bearings 288 which support the shaft 288 which pass through horizontal slots 285 formed in the bracket 2. The arrangement is such that the screws 282 may be screwed in or screwed out tomove the roller 288 against the belt 281, and so properly tension the belt 281.

The operation of the device is as follows:

The electric motor II8 indirectly drives the vertical shafts I28 which indirectly drive the shafts I25 on which the counter pressure drums are mounted. The gears 88 of each printing unit 88 drives the cylindrical forms 88 and the furnishing rollers 88. The web I88 is moved through the printing machine by the action of the transmission gears 281a and 2811; which drive the feeding rollers I58. The web I88a is assisted in its motion by the driven feeding roller I88 which is worked by the'gears 288a and 288b, the llatiter being mounted on one of the driven shafts The hand wheel 52 may be turned through a limited distance as controlled by the projection If desired these gears may be moved out of mesh, simultaneously, by lifting the pawl 55 and further turning the hand wheel 52. Or, these gears 45 and 46 of any particular printing unit 34 may be disconnected individually by the operation of their associated handle 59. The cooperative feeding rollers I85 and I82 which act against the feeding rollers I50 and I, respectively, may I be simultaneously moved out of operative positions and replaced, by the operation of the'handle I13.

The various heating units, which may be identifled by noting their frames I18, I88 and 205, may be individually moved into and out of operating positions to assist in drying the inks which are During the operation of the printing machine the web Ina is being collected on the rewind roll I39 which is arranged on a driven rewind drum II I.
